The influence of the implantation sequence on the defect and implant distri
bution during (SiC)(1-lambda)(AlN)(x) formation was studied by Rutherford b
ackscattering spectrometry/ion channelling (RBS/C) and elastic recoil detec
tion. It is shown that the implantation sequence aluminum followed by nitro
gen lead to an improved crystallinity compared to the reverse implantation
sequence for implantation temperatures above 300 degrees C, The results obt
ained are discussed in relation to the defects distributions calculated by
using a developed model which includes the effect of stress self-consistent
ly. (C) 2000 Elsevier Science B.V, All rights reserved.
